The ViDA VAT rules for online travel platforms will change the point at which some travel marketplaces become responsible for VAT. For qualifying European Union (EU) bookings, a platform may have to charge, collect and pay the VAT that the underlying accommodation or transport provider would otherwise have accounted for.
That creates more than a future reporting obligation. The platform will need to know, at the time of booking, where the service takes place, what is being supplied, the VAT status of the provider and which rate applies. The answer may also affect the price shown to the customer and the amount passed to the provider.
The measures are due to apply from 1 July 2028, although individual Member States can delay the deemed-supplier rules until 1 January 2030. Online travel platforms therefore need a readiness plan that can accommodate different national start dates rather than one EU-wide switch-over.
The ViDA change in one sentence
Where a platform facilitates an in-scope EU travel service and the underlying provider does not charge the VAT due, ViDA can treat the platform as though it received the service from the provider and supplied it to the customer itself.
The platform-economy rules cover two travel categories:
- Short-term accommodation in the EU, where the uninterrupted rental to the same person is no more than 30 nights
- Passenger transport by road within the EU
The location of the underlying service is what matters. A UK or other non-EU platform can be within scope even if it has no EU headquarters. If it facilitates a qualifying EU booking, it needs to assess the rules in the country where that supply is taxed.
Start with the platform’s role today
Before considering ViDA, a travel business must establish whether it acts as principal, undisclosed agent or disclosed agent. The legal terms matter, but so do the booking journey, customer messaging, payment flow and what happens in practice.
A platform buying and reselling travel in its own name as principal, or acting as an undisclosed agent, may fall within the Tour Operators’ Margin Scheme (TOMS). For a UK-established business using UK TOMS, VAT is generally due on the margin relating to UK travel, while the margin relating to travel enjoyed outside the UK is zero-rated. Local rules and possible obligations overseas still need to be considered.
Under a disclosed agency model, the travel provider supplies the customer and the platform accounts for VAT on its commission where required. UK VAT may not be due on some commission charged to overseas business customers or connected with overseas travel, but the outcome depends on the commercial and contractual facts.
ViDA does not replace this analysis. It adds another treatment to the mix. A platform that is a disclosed agent in commercial terms can become the deemed supplier for selected EU accommodation or road-transport bookings.
When does deemed-supplier VAT apply?
The new treatment is aimed at electronic interfaces that facilitate the transaction. A marketplace through which the parties can complete a booking is more likely to be caught than a website that only advertises an offer or redirects the customer to a provider’s own site. The practical influence of the platform over booking, payment and delivery must be reviewed.
Even where the platform facilitates the booking, the underlying provider will normally remain responsible for VAT if it gives the platform a VAT identification number for the Member State where the VAT is due and declares that it will charge that VAT. If the required number and declaration are not available, the platform may have to apply the deemed-supplier treatment.
This means the VAT result can differ between two providers offering similar rooms or trips through the same platform. The booking engine needs reliable supplier-status information before it can select the correct tax treatment.
Supplier onboarding becomes a VAT control
A supplier’s VAT number can no longer sit in a profile simply as a reference field. For in-scope bookings, it can determine who accounts for VAT. Platforms will need a controlled process to collect the correct number and declaration, validate them and retain the evidence used for each treatment.
The control design should answer practical questions such as:
- Which VAT identification number is required when a provider supplies in more than one Member State?
- How will the platform detect an invalid number, a deregistration or a change in supplier status?
- How often will supplier information be rechecked, and who owns the exceptions?
- Can the booking record show which evidence supported the VAT result at that point in time?
- What happens to future bookings when a provider’s VAT status changes?
A one-off onboarding check is unlikely to be enough. Providers may register, deregister or begin supplying in additional countries, so the platform needs monitoring and change controls as well as initial validation.
The tax decision must work at booking speed
For high-volume platforms, manual review cannot be the normal route. The booking, ERP and tax systems may need to combine several data points in real time: the location and duration of the service, the provider’s VAT status, the operating model, the customer price and the applicable rate in the relevant Member State.
The same logic must work when a booking changes. Cancellations, partial refunds, amendments and supplier-status updates need clear rules so that the customer document, provider settlement and VAT reporting remain aligned. Exception reporting will also be important where information is incomplete or contradictory.
The One Stop Shop (OSS) may simplify reporting for some transactions and reduce the number of local registrations required. It does not solve the underlying tax-determination problem. The platform must still identify the correct transaction, rate and evidence before the amount can be reported through OSS or another route.
One platform may need three VAT models
Travel platforms rarely have a single, uniform revenue stream. The same group may sell some services in its own name, earn commission on other bookings and become a deemed supplier only for a defined subset of EU transactions.
In practice, the business may need to operate:
- TOMS for qualifying travel services sold as principal or undisclosed agent
- Normal VAT rules for disclosed-agent commission
- ViDA deemed-supplier VAT for qualifying EU short-term accommodation and passenger transport by road
A transaction for which the platform is treated as the deemed supplier is intended to sit outside the EU special margin scheme for travel agents. Other sales can remain within TOMS or the agency rules. Mapping by legal entity, revenue stream, supplier type and country will therefore be essential; a high-level label such as ‘travel platform’ is not enough to drive the VAT result.
Pricing, contracts and ownership also need attention
When the platform becomes liable for VAT, the commercial impact depends on whether prices are treated as VAT-inclusive or VAT-exclusive and how the supplier agreement allocates the cost. If a provider has not allowed for VAT, the liability could reduce the supplier’s net receipt, increase the customer price or affect the platform’s own return.
Terms and onboarding materials may need to set out what VAT information a provider must supply, when it must be updated and what happens if it is wrong. The business should also agree how tax is handled for refunds, cancellations and later adjustments.
No single team is likely to own the whole answer. Tax and finance may define the treatment; legal and commercial teams manage provider terms; product and technology teams build the booking logic; and operations manage exceptions. A named programme owner and controlled decision process will help keep these workstreams aligned.
What should online travel platforms do now?
The legislation allows time, but platforms may need long lead periods to change supplier journeys, contracts, tax engines and reporting. Early work should focus on understanding the size of the change before committing to a technology solution.
- Document when each part of the business acts as principal, undisclosed agent or disclosed agent
- Identify EU accommodation of no more than 30 nights and passenger transport by road that may be in scope
- Map the countries involved and track whether each adopts July 2028 or delays to January 2030
- Assess whether supplier VAT numbers and declarations are complete, valid and monitored
- Test whether current systems can switch treatment when supplier status or booking facts change
- Review gross and net pricing, provider settlements, customer documentation, refunds and adjustments
- Decide which VAT registrations, OSS reporting and data-submission obligations may apply
- Create a cross-functional roadmap with accountable owners, milestones and change controls
A useful first output is a transaction map showing the current VAT treatment, the possible ViDA treatment, the data needed to reach that answer and the system or team responsible. That provides a practical basis for prioritising markets and investment.
